I have had my check engine light on for some time now, and I check it frequently, which it always codes a 0902... so I reset it and go on with my business... call it dumb I guess but I figured it may be because of my straight pipe...
Well today, I check the code its throwing out and to my suprise, the 0902 is no longer showing...BUT there are 4 codes now... 0705 EVap emmisions leak, 0707 downstream oxygen sensor slow response fault, 0903 EVAP canister vent control circuit fault, and the 1305 Fuel Pump control module or circuit fault...

I havent gone about troubleshooting these codes yet but I was wondering on the 1305--- would this be the fuel sending unit?? Anybody experience this problem??

I'm thinking all these codes may be related and fixing one may erase the remainder(I could be wrong though)... but I wont be able to know until it is solved.

Can anybody help me regarding 1305 code... thanks in advance!!

 

Anyone!?

 

Help on any of these codes!? Havent had time to check it out, but any advice would help!

 

I have 0705 and 0903 for a few months. You can read the stickies- there is a nice explanation of the codes http://forums.maxima.org/showthread.php?t=104931 (read in the middle of that page).

I found that the 0705 is due to other problems of evaporative system and if you fix them 0705 will disappear. In my case the 0903 turns on and off but the 0705 stays on constantly. I took the canister vent control valve out and put some oil on it but it didn't help. One member told me that he replaced the Evap canister and two of those codes went away. I'm gonna go to a junk yard to look for a cheap canister.

Regarding 0707 , it's a rear o2 sensor behind the Cat. Get it on eBay for $28 shipped. I'm gonna go to mechanic to install it because you have to put the car on a lift .

Replace the O2 sensor first and then look for a used canister and then reset the ECU. Hopefully the other codes will go away.
